Question

7. The angles of a quadrilateral are (5x), (3x + 10), (x - 20) and (x + 25)". Find (1) the value of a
and (ii) the measure of each angle of the quadrilateral.​

Answer 1

Answer:

$(5x) +( 3x + 10) +( x - 20) + (x + 25) = 360 \\ \\ = > 5x + 3x + 10 + x - 20 + x + 25 = 360 \\ \\ = > 10x + 35 - 20 = 360 \\ \\ = > 10 x = 360 - 10 = 350 \\ \\ = > x = \frac{350}{10} = 35$WE GOT X=35°

NOW 5X=5×35=175°

THIS WAY PUT THE VALUE OF X YOW WILL FIND ANGLES.
